| Question | Answer |
| Earth's solid, rocky surface containing two continents and ocean floor | Crust |
| Hot, molten rock below Earth's surface | Magma |
| The idea thar earth's surface is broken into plates that slide slowly across the mantle | Plate tectonics |
| The layer beneath earth's crust | Mantle |
| The sliding of a denser ocean plate under another plate when they collide | Subduction |
| A huge crack in the earth's crust at or below the surface, the sides of which may show evidence of motions | Fault |
| The point where an earthquake starts as rocks begin to slide past eachother | Focus |
| A sensitive device that detects the shaking of eath's crust during an earthquake | Siesmograph |
| The point on earth's surface directly above the focus of an earthquake | Epicenter |
| The amount of energy released by an earthquake | Magnitude |
| The central opening in a volcanic area through which magma may escape | Vent |
| Magma that reaches Earth's surface and flows out of a vent | Lava |
| A cuplike hollow that forms at the top of a volcano around the vent | Crater |
| A very hot part of the Sun's mantle, where magma can melt through a plate moving above it | Hot spot |
| A steep-sided cone that forms from explosive eruptions of hot rocks, ranging from particles to boulders | Cinder-cone volcano |
| A wide, gently sloped cone that forms from flows of lava | Shield volcano |
| A cone formed from exlposive eruptions of hot rocks followed by a flow of lava, over and over | Composite volcano |
| Heat from below earth's surface | Geothermal energy |
| Name three kinds of fault | Normal fault, Reverse Fault, and Strike-Slip |
| What does the Ricter Scale measure | The energy released in an earthquake |
| What does the Mercali Scale measure | The damage and destruction an earthquaked has caused |
| Shaking of the earth's crust after the initial shaking of an earthquake | Aftershock |
| What kind of data does a seismograph show | Patterns in the waves that arrive |
| What are the parts of a seismograph | Recording paper, revolving drum, spring, pen, heavy mass |
| How are data recorded on a seismograph | The pen on it moves up and down caused by the motion of earth during an earthquake drawing lines on the recording paper, indicating the strength of the earthquake |
